Generalization of wind-induced loading between two tall buildings

Abstract

Codification of wind loads with interference effects among the grouped tall buildings is an issue in wind engineering. However, it is difficult to codify a guideline or codification because of the complex nature of the problem and the large number of variables involved. Apart from this complexity and difficulty, generalized and simplified guidelines for structural design wind loads will be useful in estimating approximate structural wind loads on tall buildings in preliminary design. In this study, interference effects on mean wind loads and dynamic wind loads between two buildings were investigated though wind tunnel tests. To reach some critical conclusions that could be used to improve a design code, Design Interference Factor (DIF) on wind loads was suggested for the assessment of wind-induced interference effects between two tall buildings. number of variables involved.
